There's seduction and then there's seduction:-
1. Look her straight in the eye and keep contact, tell her she looks nice.
2. Mirror image her responses without knowledge.
3. Be attentive to her words and agree with her and sit forward slightly showing you are listening to every word.
4. If she's just come from a bad relationship try to get her to say a few words on it and then show you feel for her, he shouldn't have done that, you understand.
